THE METHOD AND SOLUTION OF DATA TRANSMISSION FROM THE TRANSPONDER TO THE READER, ESPECIALLY IN PAYMENT SOLUTIONS WITH A MOBILE COMMUNICATION DEVICE

摘要

During transmission the transformer connection coefficient can have the value k=0.2-0.001, while the antenna (3) of the receiver (2) is tuned narrowly to the transmitter's (2) frequency without considering the subcarrier frequency. The transmitter is preferably located on a memory card or on a card with a format and interface of a memory card, e.g. micro SD.
